feat: Drop typst support

Although typst is an interesting project, TeX has vastly superior
typesetting and a significantly larger repository of existing packages
and knowledge to extend upon.

I faced auto-updating issues with typst that weren't present with
vimtex, and TeX in general has better support for auto-completions due
to its \backslash usage.
